GEORGE W. BENTLEY, county, New York, applied to use,

of Brooklyn, Kings have invented, made, and a new and useful Machine for Cans, of which the following reference being bad to the specification, and to the letters of reference marked thereon, in which- Figure his a .side elevation of our inven- Fig. 2 is a top View of the same.

Thenature of the present invention consists in certain improvements, as more fully hereinafterdescribedfin the construction of a machine, for seaming metal cans; the object of the invention being the production of a machine for the purpose of seaming metal cans, by which the same shall be rapidly andeconomically' accomplished.

To enable those skilled in the arts to make and use our invention, we will describe the construction and operation of the same.

'A shows a frarneformed of any suitable material, preferably of iron, for supporting the working parts of the machine. The frame A has mounted upon it, properly positioned, thev uprights B B for supporting the shafts O and 0 The uprights B are provided with open ings 12, through which the shaft 0 passes, and the uprights B arehollowed to receive the shaft 0 andprovided with cap-pieces c, by which the shaft 0 is kept in position. '0 is a shaft inserted in the openings 1), in the uprights B, and free to slide to and fro in the same. This shaft. 0 has secured upon its forward end a disk of metal,D, or the d'iskmay be shipped over the shaft 0 and allowed to revolve upon the same, being retained in position byla collar passed over the end of the shaft, and retained in position by a set-screw.

attached to the end upright B, and F is a lever provided with a bandle, G, pinned, as at f, to the plateof metal E,

passingalso through an and fastened, as, at g, to the shaft G. This lever F moves freely upon the pin f,and by moving it forward orback, as desired, a recipe. rocating movement is imparted to the shaft O." G is a shaft supported by the uprights B and retained. in position by the cap-pieces c. This shaft 0 has secured upon its forward end a disk of metal, H, having its face hollowed, and provided with a projectingrim, as I clearly shown ings, while at crank, I, so that it may be turned by hand, or a pulley, J, may be held upon the shaft so that it may be driven by power, if desired.' K are standards securedto the bed of the frame in Figs. 3and 4 of the draw- A, having their upper ends hollowed about centrally toreceivethe rounded. ends ofa cross-piece, L, maintained in position in the standards K by the cap-pieces 1., Through the center (properly opened'toreceive it) of this cross-brace L is inserted the shaft M,

N, the plate N being supported by and attached to the cross piece L by means of a 1 plate of metal or cap-piece, 0, let into the grooved portions of the plate N and. crosspiece L, and secured to them by means of screws. Upon the end of this shaft M is held a flanged roller, P, and the shaft M is sopositioned that the roller 1? will he brought directly over or above the disk portion of the roller P projecting over or beyond the rim of the disk H. Attached upon one side of the plate end of said rod passing through the bedplate of-the frame A, and to the same a treadle may be attached if desired. A spiral spring, R, is passed over the rod Q, and retained in position by the collars upon. the rod between which it is placed.

Such being the .construction, is as follows: That our invention may be fully understood, a description of thernetal can made by us, and to the seaming of which our invention is more particularly applicable, is now introduced. The can is composed of a the operation section of a cylinder having its ends rolled over, and that a bottom and top may be united to this section of a cylinder, having, its ends rolled over, our machine may be more particits' opposite end is attacheda opening in the-plate N is a rod, Q, the lower ularly employed. The top or bottom to be united to the section of a cylinder forming the body of a can consists of a disk of metal having its outer edge turned up at right angles to the body. The section of a cylinder forming the body of a can, and having its ends rolled over,haseitherthe bottom orthe top formed of the disk of metal having its outer edge turned up at right angles to the body, placed over the end of the body of the can by the operator, and is then placedupon the ma-.; chine, the bottom or top, as the case may be, being received within the hollowed portion of the disk H. Motion isthen imparted to the shaft C upon which the disk H is-secured,

either by turning the crank 1, or by connect ing the shaft 0 with a suitable motor by a beltpassed overjhe pulley J. The fianged 1 roller P is then; brought down for-operation; .hydepressing the cross-brace L and the-plate N, -sup,por.ting the shaft M through the-rod- Q, ;to;which may be -.;attac hed a treadle, a-nd theshaft continuing to revolye and thetcan,

and top orbottom,be ing,held inposition within: the hollowed disk,H,,the flanged .portion 0f.

, volves and-turns theesameudown -npon ;.th e 1 :rolled, end ofuthe body ofthe can, and, thus seams; the metal.

seamed to the body of the can,,and a bottom When a top has I been 5 .is-tobe seamed tothe same, or-yiceversa, in 1 order that the :can, and disk, of metal may be held in position for the seaming process, the a o disk D may be thrown forward by moving, forward the shaft (3 by means of the lever F pinned upon the plate of metal E, and the disk is brought forward until it bears upon the seamed end of the can. As the shaft M is depressed through the rod Q the spiral springR is contracted, and when the foot of theoperator-is removed from the treadle the expansion of the spring 3- causes the shaft to return to its former position.

'By the use of a machine constructed as described, the seaming is expeditiously and cheaply accomplished, and much labor is saved.

Having ,now set .forth :our invention, what combination ofa hollowed disk, E[,supported upon a revolvin g shaft, 0 a flanged roller, 1?, supported by a rock-shaft, M, a disk, D,-s upported by the shaft 0, and a frame, A, constructed and operating,substantially .asand for the-purposesset forth,
